So i have been going to this new curses for a couple of months and im in class with 15 other people. My problem is that they are always trying to talk to me. They always ask personal questions ,what i did for the weekend,whats my relationship status and other personal shit that a college shoud not ask in my opinion. If im talking to them its only related to our projects and not my personal life,if they ask me something i just end the conversation politly. How do i let them know that i am not interest in talking or to hanging out with them(they invited me for a few times to hangour ,drink ,grab a coffe)besides work we do toghter. I tryed everyrhing being polite,being rude,aloof,not caring even insulting they cant leave me alone. How to get them of my back i am just not interested in there company.
